The dracut howto proposed to boot from the root dataset of a pool.
Apart from this giving problems when booting (as the code seems to
expect a child dataset and creates an illegal dataset name when using
the root dataset) the technical limitations of the root dataset
(among others the inability to rename or destroy through the `zfs`
command) resulted in the general consensus to only use it as a
container for the datasets in the pool - not as a filesystem itself.
Removed the idea to boot from the root dataset.

Now that 'pyzfs' is part of the ZFS codebase, it should be
versioned the same as the rest of the source tree. This eliminates
confusion on what version of the bindings are being used, especially
for dependent Python projects that may use the Python dist metadata
to identify compatible versions of pyzfs to work from.
In addition, a trivial change to drop the unused requirements.txt

Almost all of the Python code in the respository has been updated
to be compatibile with Python 2.6, Python 3.4, or newer. The only
exceptions are arc_summery3.py which requires Python 3, and pyzfs
which requires at least Python 2.7. This allows us to maintain a
single version of the code and support most default versions of
python. This change does the following:
* Sets the default shebang for all Python scripts to python3. If
only Python 2 is available, then at install time scripts which
are compatible with Python 2 will have their shebangs replaced
with /usr/bin/python. This is done for compatibility until
Python 2 goes end of life. Since only the installed versions
are changed this means Python 3 must be installed on the system
for test-runner when testing in-tree.
* Added --with-python=<2|3|3.4,etc> configure option which sets
the PYTHON environment variable to target a specific python
version. By default the newest installed version of Python
will be used or the preferred distribution version when
creating pacakges.
* Fixed --enable-pyzfs configure checks so they are run when
--enable-pyzfs=check and --enable-pyzfs=yes.
* Enabled pyzfs for Python 3.4 and newer, which is now supported.
* Renamed pyzfs package to python<VERSION>-pyzfs and updated to
install in the appropriate site location. For example, when
building with --with-python=3.4 a python34-pyzfs will be
created which installs in /usr/lib/python3.4/site-packages/.
* Renamed the following python scripts according to the Fedora
guidance for packaging utilities in /bin
- dbufstat.py -> dbufstat
- arcstat.py -> arcstat
- arc_summary.py -> arc_summary
- arc_summary3.py -> arc_summary3
* Updated python-cffi package name. On CentOS 6, CentOS 7, and
Amazon Linux it's called python-cffi, not python2-cffi. For
Python3 it's called python3-cffi or python3x-cffi.
* Install one version of arc_summary. Depending on the version
of Python available install either arc_summary2 or arc_summary3
as arc_summary. The user output is only slightly different.

Unfortunately, dracut and initramfs-tools do not actually get the
quotes from the cmdline. If we use root=ZFS="root pool/filesystem
name" the script still only sees root=ZFS=root and no quotation
marks.
Because + is a reserved character in ZFS, it's used as a

root=ZFS=root+pool/filesystem+name will properly expand by

libzfs_core is intended to be a stable interface for programmatic
administration of ZFS.
This wrapper provides one-to-one wrappers for libzfs_core API functions,
but the signatures and types are more natural to Python.
nvlists are wrapped as dictionaries or lists depending on their usage.
Some parameters have default values depending on typical use for
increased convenience.
Enumerations and bit flags become strings and lists of strings in
Python.
Errors are reported as exceptions rather than integer errno-style
error codes. The wrapper takes care to provide one-to-many mapping
of the error codes to the exceptions by interpreting a context
in which the error code is produced.
Unit tests and automated test for the libzfs_core API are provided
with this package.
Please note that the API tests perform lots of ZFS dataset level
operations and ZFS tries hard to ensure that any modifications
do reach stable storage. That means that the operations are done
synchronously and that, for example, disk caches are flushed.
Thus, the tests can be very slow on real hardware.
It is recommended to place the default temporary directory or
a temporary directory specified by, for instance, TMP environment
variable on a memory backed filesystem.

The on-disk format for encrypted datasets protects not only
the encrypted and authenticated blocks themselves, but also
the order and interpretation of these blocks. In order to
make this work while maintaining the ability to do raw
sends, the indirect bps maintain a secure checksum of all
the MACs in the block below it along with a few other
fields that determine how the data is interpreted.
Unfortunately, the current on-disk format erroneously
includes some fields which are not portable and thus cannot
support raw sends. It is not possible to easily work around
this issue due to a separate and much smaller bug which
causes indirect blocks for encrypted dnodes to not be
compressed, which conflicts with the previous bug. In
addition, the current code generates incompatible on-disk
formats on big endian and little endian systems due to an
issue with how block pointers are authenticated. Finally,
raw send streams do not currently include dn_maxblkid when
sending both the metadnode and normal dnodes which are
needed in order to ensure that we are correctly maintaining
the portable objset MAC.
This patch zero's out the offending fields when computing
the bp MAC and ensures that these MACs are always
calculated in little endian order (regardless of the host
system's byte order). This patch also registers an errata
for the old on-disk format, which we detect by adding a
"version" field to newly created DSL Crypto Keys. We allow
datasets without a version (version 0) to only be mounted
for read so that they can easily be migrated. We also now
include dn_maxblkid in raw send streams to ensure the MAC
can be maintained correctly.
This patch also contains minor bug fixes and cleanups.

The initramfs script was not honoring canmount=off. With this change,
it does. If the administrator has asked that a filesystem not be
mounted, that should be honored.
As an exception, the initramfs script ignores canmount=off on the
rootfs. The rootfs should not have canmount=off set either. However,
mounting it anyway seems harmless because it is being asked for
explicitly. The point of this exception is to avoid the risk of
breaking existing systems, just in case someone has canmount=off set on
their rootfs.
The initramfs still mounts filesystems with canmount=noauto. This is
necessary because it is typical to set that on the rootfs so that it can
be cloned. Without canmount=noauto, the clones' duplicate mountpoints
would conflict.

For filesystems that are children of the rootfs, when mountpoint=none or
mountpoint=legacy, the initrafms script would assume a mountpoint based
on the dataset path. Given that the rootfs should have mountpoint=/ and
mountpoint inheritance is is the default behavior of ZFS, this behavior
seems unnecessary. In any event, it turns mountpoint=none into a no-op.
That removes this option from the administrator, and if someone uses it,
it does not work as expected. Worse yet, if the mountpoint directory
does not exist (which is the typical case for mountpoint=none), the
mounting and thus the boot process will fail. For the case of
mountpoint=legacy, the assumed mountpoint may not be the correct value
set in /etc/fstab.
This change makes the initramfs script not mount the filesystem in
either case. For mountpoint=none, this means we are correctly honoring
the setting. For mountpoint=legacy, there are two scenarios: If
canmount=on, the filesystem will be mounted by the normal mechanisms
later in the boot process. If canmount=noauto, the filesystem will not
be mounted at all, unless the administrator has done something special.
If they're not doing something special and they want it mounted by the
initramfs, they can simply not set mountpoint=legacy.

ZFS already sets elevator=noop for wholedisk vdevs (for all pools), but
typical root-on-ZFS installations use partitions. This sets
elevator=noop on the disks in the root pool.
Ubuntu 16.04 and 16.10 had this. It was lost in 17.04 due to Debian
switching to this upstream initramfs script.

Automatic dependency resolution is unreliable on many systems.
Follow suit with existing code, and explicitly include icp
in module dependencies.

* PBKDF2 implementation changed to OpenSSL implementation.
* HKDF implementation moved to its own file and tests
added to ensure correctness.
* Removed libzfs's now unnecessary dependency on libzpool
and libicp.
* Ztest can now create and test encrypted datasets. This is
currently disabled until issue #6526 is resolved, but
otherwise functions as advertised.
* Several small bug fixes discovered after enabling ztest
to run on encrypted datasets.
* Fixed coverity defects added by the encryption patch.
* Updated man pages for encrypted send / receive behavior.
* Fixed a bug where encrypted datasets could receive
DRR_WRITE_EMBEDDED records.
* Minor code cleanups / consolidation.

On Void Linux (x86_64 musl) libgcc_s.so is located in "/usr/lib"
so it is not found by dracut and it produces an error.
Add a simple additional path check for "/usr/lib/libgcc_s.so*"
and install it in the initramfs.
